Newsletter 30 April 2021

Currently, there are many variants on the flexible bag in box packaging market in terms of structure and types of film used in the production process. One of the two most popular are packaging made of either a barrier film based on ethylene copolymer and vinyl alcohol (EVOH foils) or a laminate based on metallized polyethylene terephthalate (Met-PET foils).


EVOH-based films are highly flexible and highly resistant to cracking. From an aesthetic point of view, this foil is usually transparent. One of the main properties of the EVOH film is its barrier to atmospheric gases (nitrogen, oxygen and carbon dioxide). Barrier is a parameter that determines the permeability of gases through a given material. The appropriate level of foil barrier ensures that the packaging will be suitable for storing, among others food products, thus extending their shelf life. The limited migration of gases into the interior and from the packaging guarantees the desired organoleptic qualities of the stored products. The limited access of oxygen delays the aging process and effectively blocks the growth of microorganisms in the product. The current technological possibilities allow for a wide range of modifications in the composition and structure of EVOH foil, towards a significant increase in the barrier to gases, strength and color of the foil itself.


In turn, the laminated foil based on metallized PET, apart from similar gas permeability properties to EVOH foil, is characterized by a barrier to light radiation (especially UV). This is important when the stored product is particularly prone to aging under the influence of UV and requires additional protection against light. Met-PET film is often used by customers who fill in aseptic conditions, because the thermal sterilization process in the area of ​​the collar in bags made of Met-PET film is more efficient (slower degradation of the film). At present, the production process of EVOH film and functional additives allows the available types of EVOH film to compete with Met-PET film. Thus it is possible to produce packaging that meets the requirements of aseptic filling and thermal sterilization. Additionally, unit carton is a common method of storing filled bags. This type of outer packaging ensures complete lack of light access at every stage of the logistics process.


So which foil should you choose?


One of the key parameters in assessing the suitability of the packaging for storage purposes is its barrier properties, which can be ensured by the use of an appropriate carrier such as EVOH, Met-PET and many others. In laboratory conditions, it is possible to determine the barrier level of a given package with high accuracy. However, in reality, the production (filling, packaging), logistic (storage and storage conditions, transport, distribution) and technical operations (treatment by the target customer, storage conditions, etc.) significantly affect the durability and functionality of the packaging. Years of experience and tests carried out in laboratory conditions (transport tests and simulations with the use of vibration methods) have proved significant differences in the durability of packaging made of EVOH film compared to Met-PET film. In particular, we are talking about the number of generated microdamages, which significantly affect the deterioration of foil mechanics (foil strength) and worsen the barrier properties of the package. One of the methods of testing the susceptibility of film and entire packaging to durability throughout the distribution process is the Gelbo method. It consists in cyclic twisting a sheet of foil through an angle of 460 °. The foil sheets treated in this way are then checked for the number of microdamages or the level of oxygen permeability (OTR). Below we present the results of our tests carried out on EVOH film and Met-PET film. The samples were subjected to 900 cycles and examined for the number of microdamages.



           EVOH FOIL                                         MET-PET FOIL


Analyzing the above results, it can be concluded that the number of microcracks in the EVOH film is much lower than in the case of Met-PET film. Thus, it is confirmed by the argument that EVOH film can, under certain conditions, successfully replace Met-PET film.



Another important factor in choosing the right packaging is its possible environmental impact. Especially now, when there is a growing awareness of users about the fate of used packaging, the method of recovering secondary raw materials or potential environmental fees (e.g. the fee for extended producer responsibility). Based on the recommendations of the RecyClass group, we can conclude that flexible packaging made of Met-PET film will be classified as low compatibility (D-E-F) due to the difficult process of post treatment towards obtaining secondary raw materials. At the same time, packaging based on EVOH film (classified as limited capatibility C-D), can in most cases be further processed to recover, among others, polyethylene (LDPE).


Based on our experience and the collected knowledge, increasingly bag in box packaging made of Met-PET film is converted into packaging made of EVOH film while maintaining full functionality and durability of the packaging.

Ladies and gentlemen,

For some time we have noticed that the market of raw materials, including plastics, has a clear tendency to increase prices. The production capacity for PE and PP granules is limited for various reasons that are reported by suppliers and manufacturers on an ongoing basis.

Among the most frequently mentioned are production problems, such as unexpected failures or technological difficulties. We have noticed production downtime in petrochemical plants in the USA due to extreme winter. The supply of gasoline and ethylene was also limited due to lower crude oil production last year.

Another key reason is the logistic disruptions related to the COVID-19 pandemic, which translate into the suspension of deep-sea transport and an increase in prices for container freight on the Europe-Asia route. Imports to the EU were also limited due to the arbitration of exporters in the USA and Russia.

The constraints on the availability of raw materials, coupled with the continued high demand for these materials, are also of great importance.

Our Customer Service Department monitors both the prices of raw materials and the main indicators related to them on an ongoing basis. According to the ICIS portal, the price of LDPE raw material has increased over 4 months from:

48 week 2020 – EUR 1320/t LDPE


11 weeks 2021 – EUR 2000/t LDPE

This gives an increase of 51%.

For similar reasons, we can also observe an increase in prices on the paper market, mainly due to the significant demand for this product. From the information we receive, it amounts to 5-10%. Additionally, there is a deficit in the availability of selected types of paper, including for the production of cardboard.

The future is uncertain. Analysts’ forecasts for both further price increases and shortages of raw materials will persist in Q2 and Q3.

Therefore, in order for the production process to proceed without unnecessary delays, we ask you to plan orders in advance. For our part, we will do everything to meet your needs and meet the designated delivery times.

We will keep you informed about any changes.


Best regards,

Sulfuric acid, used as an electrolyte for industrial batteries, was one of the first products packed in bag-in-box that we know well today. In the era of the packaging revolution, in the 80’s, bag in box packaging was used mainly in the food industry, and since then, its increasing share in the packaging process has been observed. In the era of another packaging revolution dictated by environmental considerations, the dynamic development of modern and safe raw materials and the growing pro-ecological awareness of consumers, a dynamic increase in the share of flexible bag-in-box packaging for packaging chemicals in a broad sense is observed.


Why bag in box? Safety, Economy and Environment!


The list of chemicals is extensive. Currently, it is possible to pack substances such as adhesives, oils, chemicals, detergents, lubricants, paints or goods from the cosmetics industry, such as conditioners, lotions, shampoos and creams, into bag in box. All these products are demanding and often dangerous. The list is not exhaustive and there is an ever-growing interest in flexible packaging by chemical manufacturers from various industries.

Research and Development Centre BIBP Sp. z o.o. and its multidisciplinary, experienced team ensures that the process of selecting bag in box packaging is carried out in accordance with the standards that guarantee safety at every stage of the process: filling, storage, transport and distribution, use and disposal of empty packaging. Working in accordance with the PMI standard and Product Part Approval Process (PPAP) guarantees that the highest quality and safety standards will be met at every stage of the selection of packaging for chemicals, and that the entire creation process will be transparent and understandable to each of the parties.

The ability to access modern raw materials, quality control methods and analytical tools allows you to select components that meet the requirements of the market. The selection of materials takes into account the preservation of strength parameters measured by tests: flex cracking, drop test, burst test, etc. Great attention is paid to the stability of raw materials during the entire life cycle of the product (also when filled), through the use of aging tests, mechanical degradation, and microscopic analysis. It is important whether the packaging is subject to the ADR convention and if so, the design process takes into account the stringent requirements for this type of packaging. It is also worth mentioning a number of valves and taps compatible with the bag in box, thanks to which the dosing of the product is accurate, fast and safe, which is a key feature when dealing with products presenting a potential risk. Access to a wide base of suppliers gives extensive possibilities in the selection of taps and closures, depending on the density, viscosity and properties of a given product and the method of its dosing desired by the customer.


Bag in box closures allow for easy and problem-free dosing of the product, thus there is no excessive draining or sticking of the medium. It is also related to the fact that during use there is no risk of air or any contaminants getting inside the packaging, therefore the product does not foam and does not splash. Another factor influencing performance is the fact that the bag’s flexible material allows its contents to be almost completely emptied. This is not possible when using standard containers, often of fancy shape, where a large amount of product is wasted and thrown away by being left inside. From a broader perspective, also the transport and storage in a bag in box are much more efficient. The shape of the cuboid as represented by the bag in box minimizes the so-called dead space, whether in a warehouse or on a pallet, and at the same time maximizes the transport capacity. On the other hand, empty, used packages are folded practically flat, so even after using the product, they do not take up unnecessary space.


Another argument in favor of choosing a bag in box is that these bags have a significant impact on the waste management process.

BIB contains a much smaller amount of plastic compared to standard packaging (at least 60% less) while maintaining similar strength parameters. The individual components of bag in box packaging are recyclable even in 100%.

It is estimated that a HDPE canister with a volume of 5 dm3 (228 pieces on a EUR pallet) takes up a volume of 1.5 m3 before and after use, with the generated waste mass of approx. 35 kg (HDPE – 32.3, PP – 2.7 kg) . The same amount of empty 5 dm3 bag in box takes about 0.05 m3, and after use, these bags take about 0.077 m3 with a weight of about 10 kg PE. In this simple example, the mass of waste is 4 times smaller, and the volume of waste is nearly 20 times smaller. Of course, the costs associated with the transport of empty packaging, which are also significant, were not taken into account. Taking into account also the fact that the bag in box has a much smaller mass and occupies a smaller area, its transport and storage is more efficient. More efficient transport means lower fuel consumption, which in turn leads to less carbon dioxide emissions. Compared to bag-in-box with rigid packaging, the energy consumption is lower at every stage of production, use and disposal, and thus a lower carbon footprint during the production, filling, transport and recycling of packaging. Using dedicated tools (eg Carbon Footprint Calculator) it is possible to calculate specific values ​​for the compared types of packaging.

It should be noted that the current production technology and the development process of these packaging places great emphasis on the selection of materials so that their reuse does not generate additional costs and technological challenges. In the design process, the use of multi-material laminates is abandoned, the separation process of which is sometimes technologically impossible, the excessive amount of prints and varnishes is eliminated by replacing them with cardboard packaging (100% recyclable or reusable), and materials that would hinder the process of separate collection and processing (multi-material plastic details).

In summary

The current technological possibilities in the field of the production of bag in box provide wide opportunities for the development of packaging for the chemical industry. Based on the data from the “Bag in Box Container” report by the economic intelligence agency Grand View Research (2020, USA), dynamic development of this type of packaging is forecasted in the years 2020-2027 by up to 7% annually.

For companies and organizations consciously striving to improve the environment around us, bag in box packaging by:

  • improving the dosing efficiency
  • reduction of product losses
  • maintaining product quality
  • safe storage of the product
  • optimization of logistics costs
  • significantly lower amount of generated waste

are the perfect solution. These are the functionalities of our bag in box.

July 1 is the International Fruit Day.


It was initiated by German students in 2007. This holiday is aimed primarily at people who care about their health and promote a healthy lifestyle. Its main assumption was to eliminate all interpersonal barriers by sharing fruit, and thus creating solidarity and intercultural bond.

It is recommended to eat 5 portions of fruit a day – our team did this task above the norm on that day 🙂








At the end of June, our company was nominated to take part in the #gaszynchallenge campaign. This action is to help raise money for people who need this help the most. The rules are very simple, nominees must perform 10 push-ups or sit-ups. In case of success, they pay a minimum of PLN 5 to the selected bank account, if they fail, the minimum is PLN 10. Finally, in order to popularize the campaign, another 3 people must be assigned to the task. So we rolled up our sleeves and eagerly took up the challenge.

You can see the coverage of this event on our FB profile:





We are pleased to announce that at the end of July we became a member of the Bydgoszcz Industrial Cluster. The organization in its ranks includes companies from the tool industry and plastics processing. The main goal is to integrate the environment of toolmakers and processors by creating a network of business relations. This, in turn, helps to develop technologically.




For a long time our production has been carried out in the Ultra Clean standard. CLEAN ROOM is a place where environmental parameters are controlled, thanks to which an adequate low concentration of solid pollutants in the air is ensured. Continuous filtration of the air inside makes the bag-in-box produced in this standard ideal for storing products that are poured aseptically or after the pasteurization process. The interior of such a room is filled with air, which is forced through a special system of HEPA filters that eliminate any fractions of pollutants. Employees who want to get to the room are obliged to go through the airlock and be dressed in special protective suits, additionally they are also equipped with masks, gloves and shoe covers.
